' sweep springs ands iral springs. Fig. 3 e e alsi c v'ation, an .4 a plan of adevice conslstingof-coile springs and spiral s rings. Fi .-5 and 6 are 'like views of a evice in w ich spiral springs alone are 6t- In the form of construction shown in Figs. land-2, the axle 1 supportsthe'ordinar-y single sweep springs 2 to the ends of which, however, thebed 3 of the vehicle is 65 not directlyconnected as ordinarily, but indirectly,.by means of spring controlled belllevers, fulcrume'd'to the bed 3.' In the ex ample illustrated `two pairs of such levers i are rovided', turning on pins 4 carried by 7.0

the orked arms 5 secured to the bed 3. The ends of the horizontal and of the vertical lever-arms 6, 7 respectively of. two sulr levers areconnecte'd with each other, so that la lever-frame is foi-ined. The horizontalv 7 5 I arms 6 are secured to the ends of the springsl 2 by links 8 in Well-known manner.' Around the bolt 9 which connects the" vertical arms 7, there grips the free end of a spiral spring 10, the inner'endof which issecured to the 80 pin 4 which is secured inV the fork 5, and which forms thefulcrum for the lever him infhe' arms 6 and 7., L

he action of this deviceacanbe best ex planed by means vof the following simple 85 examples. A shock .which is directed substantially vertically-such for instance, as4 ac ts on the wheel from belowwhen the'vehicle isdriven from the .side-walk over the curbstone onto the roadwayis taken up especially bythe spring 2, in welLknown manner. v On the other hand, a shockwbich i8 directed substantially horizontally-such, for instance, as occurs when a vehicle is driven.

from the roadway onto the sidewalk, Dwing. 9 5

to the -wheel collidin ,with -the' curbstone-L will be transinl ted b the springs 2 in-hori- 'thebell-levors connected and since the leversfswing on the pins 4, spiral springs 10 will be .wound u or un' wound as `the case may be, so that t e shock is 'very considerably weakened. The vertical back-vibrations of the bed 3 are taken up at the'same time by the spiral springs 10v and' the springs 2; the horizontal vibrations,

again, by the spiral springs. The tension of the latter springs can be altered by the pin 4, after loosening the nuts of the' bolts 1 1,

being tlllnd inthe fork 5 and then ixed 110- L each wheel of the vehicle is in resilient conagain in tlienew. positionby-retighteni1ig the bolt-nuts. So far',v only theaction of vertical and horizontal shocks on the spring systemV and vehicle vhave been explained. 'It is clear, however, that shocks in all ,otherf intermediate d irections can also. be taken up .bythe'coperating springs, whichV themselves divide-the direction of action into a horizontal anda vertical part. F urthermore, the spiral springs, as already mentioned, take up all shocks running invtheir plane. In consequence, the shocks trans'- mitted to the bed of' the Vehicle are exceedingly small.

Inthe modificationsV shown in Figs. 345,

nection with the carriage-axle.

In the device shown in Figs. 3 and 4, the short'axle 13 of the wheel 14 is mounted in a frame 15, which swings on a' rod 17 against the action of the horizontally disposed s iral spring 16. The rod 17 is mounted-in b ocks in their guideways against the action of the coiled sprin s 22. Allintermediate shocks are equalize in like manner by the coperation of the two systems of springs.

i In the third modcatiomsliown i'n' Figs.

5 and 6 the wheel-axle 21 is mounted. in the saine manner as in the second modifica-tion in a frame 25, which Ilikewise turns on an axis 27 against the action of a spiral spring which axis, however, is in this case identical with the carriage-axlc. On the axis 27 is a bridge 28,. thc extremities of which are jointed to upper limbs 29 of donblearm'ed levers, fulci'unied to the carriage-,frame and whose lower limbs 30 are under the action of spiral springs 31 likewise secured to the carriage-franie. Iii this modification the vertical shocks are taken up, as before, both by the spiral spring 26 and the lateral springs 31; while the horizontal shocks are l;'oiir signatures in the presence of two Wit. horizontal shock,l for example, against the 5- wheel-axle 24:, and the carriage-axle 27 causing swinging of -the levers YL9, 30 on their l vtulci'uins androlling up or uni-olling of the lateral s rings 31.

and a, connection .between theother arm of the levers and the axle.

3. The combination with a vehicle'fraine to the frame, bell crank levers engagin with one arm the free end of the' spira springs, a leaf spring bearing in 'its medial portion upon the axle, and a connection between the ends of the leaf spring and the other arm of the bell crank lever. I

4. The combination with a vehicle frame to the frame, bell crank levers fulcrumcd to Vand its axle, a pair of spiral springs affixed.
